Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. AC/DC conversion is instead centralized, and by using efficient, fully controllable power-electronic interfaces, high ...

Renewable Energy based microgrids are being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. The technical challenges associated with the operation and controls are immense. Electricity generation by Renewable Energy Sources is of stochastic nature such that there is a demand for regulation of voltage output in order to ...

The objective of this study is to test the proposed Interconnected hybrid microgrid model with inclusion Photovoltaic Sub-System (PVSS), Wind Energy Sub System (WESS), Battery Storage (BESSS) in a DC / AC Connected which will be playing an important role analysis transition from electric grids Smart Grids Systems (SGS). In model, IEEE 14 busbar distribution systems used as case for interconnect...

In an islanded DC microgrid with multiple distributed generators (DGs), the droop control is employed to realize proportional current sharing among DGs in microgrid. The action of causes a deviation bus voltage which exacerbated by line impedance between DG and bus. this paper, advanced secondary scheme proposed simultaneously achieve accurate regulation cooperative system. controller introduce...

In this paper, a grid interface current control strategy is presented for DC microgrid, which aims to reduce the disturbance from PV generation and load variation main without converter. The directly controlled by battery DC-DC converter within microgrid. Based on comprehensive analysis of control, system has been mathematically modelled. This enabled two transfer functions be derived that refl...
